Default [Q] Upgrading Nexus 5 rooted with custom kernel to 4.4.4?

Currently running Android 4.4.3. I have TWRP installed. To upgrade can I just flash system.img and radio.img within TWRP? I believe that this is how I upgraded from 4.4.2 to 4.4.3 but my memory is hazy and this was before I installed a custom kernel. I'm not sure on whether I need to do anything additional such as rolling back to stock 4.4.3 before upgrading to 4.4.4. I've seen people discuss this but I think that's just if one wants to run the OTA update.

you can. or you can just dirty flash(no wiping) a stock rooted rom from the android development section, and your kernel, and reboot

Thanks. Is there any way to do it from recovery? I hate having to hook up the USB cable, etc.

Also, this seems a lot easier than what is suggested here (Special Scenario #1) http://forum.xda-developers.com/goog...-desk-t2523217

Quote:
1) downloaded factory image from https://developers.google.com/androi...ges#hammerhead
2) extract the tgz, the tar within that, then extract the the zip within that to get the system.img and boot.img files
3) moved these two files into the adb folder (for the fastboot/adb method)
4) downloade SuperSU-v1.80.zip from http://download.chainfire.eu/supersu
5) put SuperSU-v1.80.zip on your phone's internal storage
6) download the 4.4.1 OTA update zip from http://android.clients.google.com/pa...M.7ed504f6.zip
7) rename it to ota.zip
8) move ota.zip onto your phone's internal storage
9) boot into bootloader
10) open command prompt from your adb folder
11) connect USB cable
12) type 'fastboot devices' to check the connection
13) type 'fastboot flash system system.img'
14) type 'fastboot flash boot boot.img'
15) use volume and power buttons to boot into recovery (TWRP)
16) install ota.zip
17) install SuperSU-v1.80.zip
18) clear dalvik and cache
19) reboot phone
Seems to me like people go to a lot of extra work installing the OTA instead of the factory images.

extra work is done in both those methods. just dirty flash a precompiled rooted stock rom and your kernel. itll take seconds to a minute, and you wont lose anything. and you do that in recovery.

Not to create a flamewar but I'm too afraid of security issues to install a pre-rooted ROM.

have you ever seen or heard(a real one, not just "stories") of a security issue?

The ones on XDA are safe. Just as safe as you rooting your stock ROM.
